Been on ortho tri cyclen for about 6 months but still having spotting/ starting to have periods twice a month. my periods would be twice a month for about a week around the 4th month and in between the periods i would be spotting very lightly. how can i stop it? maybe because I'm a light smoker with hookah so it effects the pills? I take my pills every day around the same time in the morning every day. I really want the spotting to stop and having 2 periods a months. also I don't take placebo pills so does that also make me spot?
